IMPLANTABLE MEDICAL DEVICE WITH COORDINATED VENTRICULAR OVERDRIVE AND TRIGGER MODE PACING
First Claim
1. An implantable system for providing coordinated ventricular overdrive and triggered pacing, comprising:
- at least one lead for sensing signals from a heart to obtain sensed signals representative of tachycardia occurring in at least one chamber of the heart, the at least one lead including at least one electrode; and
a control module detecting tachycardia in at least one chamber of the heart and based thereon, initiating an overdrive pacing mode and a triggered pacing mode, the control module controlling delivery of overdrive pacing pulses through the electrode to a first chamber of the heart in accordance with the overdrive pacing mode, the control module controlling delivery of a triggered pacing pulse through the electrode to the first chamber of the heart in accordance with the triggered pacing mode, the triggered pacing pulse being temporally interspersed with the overdrive pacing pulses.

Abstract
A method and system are provided for providing coordinated ventricular overdrive and triggered pacing through an implantable system. A lead senses signals from a heart to obtain sensed signals representative of tachycardia occurring in at least one chamber of the heart. The lead includes an electrode. A control module detects tachycardia in at least one chamber of the heart and based thereon, initiates an overdrive pacing mode and a triggered pacing mode. The control module controls delivery of overdrive pacing pulses through the electrode to a first chamber of the heart in accordance with the overdrive pacing mode. The control module controls delivery of a triggered pacing pulse through the electrode to the first chamber of the heart in accordance with the triggered pacing mode. The triggered pacing pulse is temporally interspersed with the overdrive pacing pulses. The triggered pacing pulse may be delivered at a time that is independent of, and unrelated to, the timing of the overdrive pacing pulses.
